Silt particles are smaller than sand particles. Which of the following statements is true?

Silt has a higher terminal fall velocity than sand.
Silt has a higher threshold velocity than sand.
Silt is more vulnerable to wind erosion than sand.
Silt can't be carried by wind, but sand can.

As per given information, silt particles are smaller in size than sand. The smaller particles of silt would be lighter in weight than the larger sand particles.

The smaller and light weighed silt particles would be easily carried away with the wind as compared to bigger and comparatively heavier sand particles.
